APPARATUS FOR COATING SURFACES.

SPECIFICATION forming part of Letters Patent No. 358,849, dated March 8, 1887.

` Application filed June 26, 1886. Serial No. 206,325). (No model.)

To @ZZ whom. it may concern:

Be it known that I, ALBERT EDwARDs, a citizen'of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Process of and Apparatus for Coating Surfaces of Textile Material, of which the following is a specication.

My invention relates to an improved process of and apparatus for coating surfaces; and the objects of my improvements are, first, to provide a simple processwhereby the under surfaces of articles-such as gimps, braids, 850.-.dcan be coated with any glutinous substance without the liability of the mixture penetrating more than will be necessary for adhesion; second, to at'ford a means for coating such surfaces with expedition, so that the cost of the article so treated will not be materially increased 5 and, third, to provide as an article of merchandise gimps, braids, Src., prepared with an adhesive surface, whereby they can be applied to articles of furniture by simply moistening the said surface and bringing it in contact with such article, thus making a great saving in time and expense 0f applying the same. I accomplish these objects by the mechanismillustrated in the accompanying drawings, in which- Figure l is a perspective view of the machine. Fig. 2 is a plan view of the article coated; and Fig. 3, a plan view of a modification of the device, which represents a fiat surface with the ribs running parallel with each other.

The process consists of first coating a smooth hard raised surface, resembling a rib, with a,

glutinous substance and allowing it to become set to the proper consistcnce, but not to render it unpliant. The surface of the article to be coated is then placed on the glutinous substance and subjected to slight pressure, thereby causing the rough or uneven surfaces of the article to be pressed into the soft glutinous substance, which slightly enters the texture and'adheres to it. At the proper time the article is removed from the smooth hard surface, carrying with it the glutinoussubstance, which forms a smooth glossy coating on the under surface of the article so treated. The width of the rib is preferably made narrower than the article coated,

thus leaving a margin on each edge which is not coated on said article. The smooth hard surface causes the glutinous substance to as sume a close even surface. Consequently there 5 5 is but slight adhesion to it, and therefore readily stripped off when dry, as it closely adheres to the softer texture of the article coated.

The device for coating surfaces consists, preferably, of a cylinder, B, supported by a frame, 6o A, said cylinder having a continuous rib, l?, winding round it spirally at a constant inclination, so as to leave a like continuous groove,

S, between each turn and the next, thus providing a continuous surface of great length, and yet within narrow limits. This cylinder also produces, when revolved, motion or pressure in the direction of its length, and thereby imparts motion to two carriages, D F, which are provided with wheels N, adapted to t 7o into said groove S.

The carriage F is supported on rod C, and is provided with a receptacle, I, for holding the glutinous substance, and carries a brush, L, which is caused to bear and distribute the gluti- '75 nous substance onto the said`ribs P. Said carriage is also provided with a pendant or wheel,

N, which runs in groove S, having its bearing against the side of rib P, and by which motion is imparted to it when the cylinder is revolved, 8o causing it to travel in the direction of the length of said cylinder, and thereby spreading the glutinous substance over the entire rib surface.

The carriage D is supported on the rod C, and is provided with a pendant or Wheel, N, S5 which is adapted '4to run in groove S, having its bearing against the side ofthe rib, and by which motion is imparted to it when the cylA inder is revolved, causing it to travel in the direction of the length of said cylinder, and thereby carrying the article to be coated along with it, and directing said article, by the aid of guide H, onto the rib P of said cylinder B.

The article coated is subjected to more or less tension, which compresses it to the cylinder as it is wound on the same. The cylinder is re` volved by any mechanical device. The ribs can be coated with the glutinous substance by hand, if desired.

I am aware that it is common to use glue in ICO attaching gimp to articles of furniture but it is applied with a brush and at the tilne when it is to be attached toany article. 'Ihis method is objectionable, as the glue is liable to extend over the edge and disigure the gimp, besides some styles of gimp will not permit the brush to 5 be used for fear of the glue passing through the meshes. This, therefore, I do not claim; but I am not aware that a preparation of glue has been spread on a surface and allowed to become properly set, and then pressing the ar- Io ticle to be coated onto the said glutinous surface, and at the proper time stripping the article off, bringing the glutinous substance With it, before my invention.

I do not Wish to be understood as confining I 5 myself to a narrow raised surface for spreading the glutinous substance on, as I can use a broad flat surface when Wide articles are to be coated singly equally as Well.

What I claim, and desire to secure by Let- 20 ters Patent, is-

1. The method of coating articles described, consisting in coating a smooth hard surface become set to a proper consistence, then placing the article to be coated on the said gluti-fnous substance and subjecting it'to slight pressure, thereby causing the rough or uneven surface to be pressed into the soft glutinous substance, ,Which slightly enters the texture and adheres to it, then stripping the article from the surface, carrying with it the glutinous substance, which forms a smooth glossy coating on the under surface of the article so treated, as set forth.

2. In an apparatus for coating surfaces, the cylinder B, provided with rib P, groove S, and the means for guiding the article to be coated onto said cylinder, substantially as and for the purpose set forth.

ALBERT EDWARDS.
